Aerator Installation At Connected Faucet; Electrical Connection - Stiebel Eltron DHC-E 3/3.5-1 Trend Utilisation Et Installation

INSTALLATION
Installation
Make certain that the cold water supply line has been flushed
to remove any scale and dirt.
Install shut-off valve in cold water line as shown in the illus-
tration on page 15. This allows the unit to be easily isolated for
maintenance purposes.
Connected braided steel flex connectors (recommended for hot
outlet, required for cold inlet, not supplied) to the twin ½˝ NPT
male connectors.
Open the shut-off valve in the cold water inlet line.
When all plumbing work is completed, check for leaks and take
corrective action before proceeding.

11.3 Aerator installation at connected faucet

DHC-E 3/3.5-1 Trend ships with a 0.5 gpm (1.9 l/min) pressure com-
pensating flow-reducer/aerator that must be installed on the faucet
the water heater is connected to. Failure to install the aerator may
result in lower water temperatures than desired.
DHC-E 4/6-2 Trend ships with a 1.0 gpm (3.8 l/min) aerator and 2 x
0.5 gpm (1.9 l/min) aerators, allowing for maximum installation flex-
ibility. A single 0.5 gpm or 1.0 gpm aerator (depending on required
temperature rise) should be installed when the unit is used at the
[low] power output setting (jumper position 1). At the [high] power
output setting (factory default, jumper position 2), the unit may be
plumbed to a single sink using the 1.0 gpm aerator, or to two sinks
using the 2 x 0.5 gpm aerators. Failure to install the aerator(s) may
result in lower water temperatures than desired.

11.4 Electrical connection

WARNING: Electrocution
Before beginning any work on the electric installation,
be sure that main breaker panel switches are "Off" to
avoid any danger of electric shock. All mounting and
plumbing must be completed before proceeding with
electrical hook-up.
The unit must be properly grounded in accordance with
state and local codes, or in absence of such codes, in
accordance with national electric code or the Canadian
electric code. Failure to electrically ground the product
could result in serious personal injury or death.

WARNING Electrocution
The connection to the power supply is only permissible as
a permanent connection in conjunction with a ¾˝ Romex
clamp. Ensure the water heater can be separated from
the power supply by an isolator that disconnects all poles
with at least 1/8˝ (3 mm) contact separation.
CAUTION: DO NOT INSTALL IN A BATH ENCLOSURE
!
OR SHOWER STALL. DO NOT CONNECT TO A
SALT-REGENERATED WATER SOFTENER OR A WATER
SUPPLY OF SALT WATER.
FOR USE ON AN INDIVIDUAL BRANCH CIRCUIT ONLY.
CAUTION: CONNECT ONLY TO A CIRCUIT PROTECTED BY A
CLASS A GROUND FAULT INTERRUPTER
USE BONDING CONDUCTOR IN ACCORDANCE WITH THE CA-
NADIAN ELECTRICAL CODE, PART I
Supply this appliance only from a grounded system. A
!
green terminal (or a wire connector marked "G", "GR",
"GROUND", OR "GROUNDING") is provided for wiring the
appliance. To reduce the risk of electric shock, connect
this terminal or connector to the grounding terminal of
the electric service or supply panel with a continuous
copper wire in accordance with the electrical installation
code.
Material losses
!
Observe the type plate. The specified rated voltage must
match the supply line voltage.
Material losses
!
The DHC-E 3/3.5-1 Trend must only be connected to a 120 V
electrical supply. Connecting the DHC-E 3/3.5-1 Trend to a
208–240 V electrical supply will permanently damage the
unit and void the factory warranty.
All electrical work must comply with national and applicable
state and local electrical codes.
The DHC-E should be connected to a properly grounded ded-
icated branch circuit of proper voltage rating. In installa tions
with several DHC-E units, each unit requires an independent
circuit. Please refer to the technical data table for the correct
wire and circuit breaker size.
